As they state it's hard to be definitive as ethnicity is not always recorded. It would appear though that there is a spike in numbers of Asians involved in "grooming gangs" in some of the data sets. (27% of perpetrators versus 8% of population) However, for overall sexual offences and sexual offences against minors the perpetrator is most likely to be a white male.

As ever, there really isn't enough of data to justify any claims about one race, nationality or religion. However there is enough of standalone statistics to throw a bit of mud.

Reality is for any victim of sexual assault in the UK, your abuser is likely to a white male: so beware them lads.
